IPROFILING ATTACHMENT FOR tllLLlN Moesel.

Application iled January 16, 1920.

To @ZZ 107mm t may concern:

Be it known that l. CHARLES l/V. citizen of the United Brooklyn, in the countyot Kings and State of New York, have invented new and useful improvements in Profiling Attachments 'for tflilling-Machines, of which the following is e speeilicetion.

This invention relates to s` profiling de# Vice which is especially adapted `tor attachment to e vertical spindle milling; machine in which a rotary cutter operates on the work of the object to be cut, and s traveling table supports the work whilel it is being` shaped.

The present invention is designed to pro` vide the machine with e :master orin or pet tern linode to move with the table, sind the motion being transmitted to the work, the cutter will shape it to the exact configuretion of the die.

An object of the invention is to provide ineens for centeringor alining the puiding means, copereting with the master yorin, so that the finished work will be en exact reproduction or duplicate of the contour of the die. v

Another object of the invention is to provide roller tracer or guide to gege or control the movement of the master forni, the

of which is practically on e line with the exis of the cutter so that the emot' position of the cutter relative to the wcrlr is' governed.

Another object of the 'invention is to provide ineens for adjusting the guide roller carrying devices in e. vertical yplane to position the roller relative to the thickness ot the master form. f

rl'he invention resides more particularly in the novel combinations hereinafter described and claiiined7 reference being Inode to the accompanying drawing in which:

The .knee een be slid up or down end controlled bv ineens or a sores7 or similar device es is well. lrnown. @n the linee isinounted a slide rest including e, saddle 8 ine-de to coact with e groove 9 perinit forward end backward movement ofthe saddle. The saddle is also provided with groove lO extending et right :ingles to the groot/'e 9 and o, table .ll slides in the groove, rlhe *foregoing arrangement p rinits the table to be inoved verticiilly up or down and horizontally slid in e longitudinal or transverse nath. rlllie above eleniente of the milling machine are well lrnown.

@n the table is srsnged o Worlr siioport consisting of tivo legs or standards 1Q best seen in n ig. 3. having en arched web 13 connesting` the standsrds. The standards secured to the table by et screws le, each being inode to block arranged in s slot l5, while tliefend ot the screwucoacts with c. tapped bore in the base of the standard. if] hen the screws ere loosened the blocks can be slid along the slot to any desired position. rlille standards Corry or :torni sn integral part olf table 16 elevated above the lower ils-ble.

The roller is rotatively mounted on' the head, as shown in Fig. t, by means of a screwA 30 having a nut 3l engaging the end of the screw, and set in a socket or counter sunk in the arm. The lstem of the screvvY passes through a bushing or sleeve 32 positioned in a bore adjacent to the socket in the arm. An oil channel 33 extends from` the top of the arm/into the sleeve to convey oil directly onto the roller. A capstan screw 34 threaded in the bracketis einployed Vto vertically adjust the guide roller carrier to bring the roller'in its, proper position with the master form and to compend sate for any Wear on the roller or form.

On the surface of the table ll is posi ti'oned a master form 35 having tapered Walls 36 to Vfit the periphery of the guide roller. Coacting With the side edges of the master form and inner flanges of the table 11` is a parallel strip V37 and on the opposite side a pair of Wedges 38 which when tightened will move the inner section against the l side of the die to jam it against the opposite member and securely cla-mp it in place on the table. l f Y The slide rest of the machinepermitsthe master form to be moved in any direction and the guide roller being in contact with the Wall of the master form, the motion will be transmitted to the Work.V A rotarycutter il inthe same vertical airis as the guide roller Will shape the WorkV to correspond'to the movement of the master form. The cut-V ter can be'mounted on a vertical spindle net shown, andl be revolved as is Well known. Any object ofra given contour or outline can be duplicated, and the guide rcller in conjunction vvith the pattern forms an auto-j matic guide for the cutter controlled by the movement ofthe tables for shaping the Work to any form. The roller being at all times in alinement with theanisof the cutter, a perfect facsimile ofthe pattern will be cut,

and the path traveled by the master forrnYV is simultaneously transmitted to the Work. By having the Work above the form and both being readily accessibleV from the front it facilitates the labor of the operator and cheapens the cost of production.

rlhe profiling device is shown applied to a vertical spindle machine, but itV will be readily understood, that it could be mounted on a horizontal spindle with slight modilisation. Y Y Y ltwill be readily understood theV above Vattachment maybe used. forV grinding pur-V poses by substituting van emery or other ,Y grinder in place of the cutting tool.
